, ARM sarE'rY LAMP.

Application filed March 1, 1924. Serial No. 696,131.

My invention relates to safety arm lamps,

- that is to lamps of a type suitable to be I templates a small and compact lamp mechanism adapted to be mounted upon.a per sons arm and used under such condition as to leave the person free to use both hands; the lamp and various parts associated with it, and including a battery whereby it is energized, being united in a single unit of compact form, so constructed so as to admit of easy production in large quantities, and made of simple parts easily obtained and readily standardized. v

My invention further includes alamp of. the general kind here contemplated, with its various parts so arranged that while the lamp is being carried upon a persons arm and in active use, the light from it is projected in three general d1rec-tions-forwardly, backwardly and sidewise, the area thus illuminated being considerable.

In addition, my invention contemplates giving the lamp such construction as to enable it to be readily held in the hand, and thus used as a flash lamp.

Reference is made tothe accompanying drawing forming a part of this specification, and in which like reference characters indicate like parts throughout the several figures.

Figure 1 is a side view of the lamp, showing it partly in elevation and partly as broken awa t Figure 2 is an elevation of the lamp, showing it from the opposite side from that contemplated from Figure 1.

Figure '3 is a section through the lamp, and is taken upon the line 3--3 of Figure 1, looking in the direction indicated by the arrows.

Figure 4 is a top plan view of the lamp, a portion thereof appearing as broken away.

Figure 5 is a perspective, showing the lamp as carried upon a persons left arm.

Figure 6 is a perspective, showing the lamp as held in a persons hand and used as a flash lamp.

A hollow casing member 7 made of sheet material, preferably metal, has the shape indicated for it in the drawing, and is rovided with a bottom plate 8, and wit a pair of straight flanges 9,10, integral with v a it, these flanges being somewhat longer than the casing member, asmaybe understood.

from Figures 1 and 2. An end cap 11 is mounted upon the flanges 9 and 10, and is spaced a little distance away from the adjacent end portion of the casing member.

The casingmember 7 is provided with a neck portion-12, set slightly inward, as may be understood from Figure 3', so as to form a shoulder 13.

FICVE.

A member 13 of translucent material such as glass, celluloid, isinglass, sheet mica or the like, and preferably having a distinctive color, such as red as here indicated, is fitted against the shoulder 13 and thus against the neck portion 12, and also into engagement with the end cap 11/ The member 14, as to form. constitutes practically a continuation of the casin member 7, as may be understood fromFlgures 2 and 3. The lower end of the translucent member '14 accord ing to Figure 3 abuts squarely against the shoulder 13 so that the outer surface of the member 14 is in exact registry with the outer surface of the casing member 7, no perceptible seam being present at the edges thus brought together. This renders the device smooth like a flask, and leaves no undesirable corners or edges protruding due to the- Joinder of the members 7 and 14 together. A plate 15 of sheet metal, carried by the casing member 7 extends like a partition across from one, side of the casing member to the other, so as to constitute a shelf within the casing. The shelf 15 carries a lamp socket 16, and detachably mounted in this lam socket is an incandescent bulb 17.

T e end cap 11 is provided with an opening 18, bounded by a Wall 19 of annular form, integral with the end cap 11 and ex- I 4 for the battery. A sliding switch button 25 of conventional form is used in connec-.

tion with the battery 23, for the purpose of turning the electric current on and off.

Mounted upon the battery casing and disposed upon opposite sides thereof are two, eyes 26, 27. A strap 28 is connected with the eye 26 and is provided with a hook 29 for detachably engaging the eye 27. The

strap 28 is used for'securing the device upon ters.

A sliding door 30, made in a-single piece of sheet metal, and concave on one of its faces and convex on the other, carries a leaf spring 31,-for pressing against the battery and holding the latter firmly in position.

By this arrangement the battery is unable to rattle or to become displaced. The door 30 carries a thumb piece 32, integral with it, for facilitating the removal and replacement of the door.

A lens 33 of clear glass ismounted upon the fiat front face of the transparent member 13. The effect of the lens is to project a strong light directlyal ead of the person carrying the lamp, thus enabling him to see to good advantage in the direction in which he is moving. This also enables the lamp to be seen plainly by persons in front of the operator. r

The lamp is carried upon the arm 34 of a person, as indicated in Figure 5. While the lamp is thus carried, the blinder lid 21 preferably covers the opening 18, as indicated by full lines in Figure 4. The blinder lid prevents the light from shiningdirectly upward into the face of the wearer, but the light can always pass out freely in three general directions, and the area thus lllum'inated is of considerable size. The operator wearing the lamp can see forwardly, and by looking around can see backwardly, while of course the light shines freely oil to oneside.

My lamp is well adaptedfor signalling, and may for this purpose be used in a number of diflerent ways.

In some instances it is desirable to use the lamp as a flash lamp. For this purpose it is carried-in the nand as indicated in Figure 6, the blinder lid 21 being in this instance shifted into such position as to leaa'e uncovered the opening 18.

My invent-ion is well adapted for use by persons in walking, or in riding bicycles or horses at night, say for instance along country roads; also, by watchmen on duty indoors or out of doors. It is well adaptedfor certain kinds of police and detective work. Itcan be used in the Army or Navy.

I do not limit myself, therefore, to any particular or special use to which the device may be employed. Neither do I limit myself to the particular mechanism here shown, nor to the precise form given to any part,' nor to any particular material to be employed in the construction or makeupof the article, except as specified in my claims, the scope of which is commensurate with my invention.

I claim- 1. The combination of a battery casing provi'dedwith a shelf extending through it and serving'as a partition, said battery easing beingfurther provided with flanges of greater length than said battery casing, an end cap,connected with said flanges, a translucent member of sheet material carried by said battery casing and engaging said end cap so as to serve as a window, said translucent member of sheet material being. so formed as to facilitate the passage. of light through it in three directions from a particular point, an illuminating member carried by said partition and located at the point just mentioned, and a sliding door engaging sald flanges and movable relatively to said battery casing for facilitating access to said battery casing and easing illuminating member.

2. A device ofthe character described comprising a casing member and an illuminating member carried by said casing member,- atranslucent member carried by said casing member and so disposed as to permit light from said illuminating member to pass out of said translucent member, an end cap carried by said casing member and partially bounding said translucent member, said end cap being provided with an opening to ermit light to pass out of said casing mem er,

and a blinder lid journaled at one of its edgesupon said end cap, said blinder lid being movable in a plane parallel with the general plane of said end cap for. the purpose of closing said opening, and means independent of said blinder cap for permitting light from said illuminating member to pass out of said casing member.

3. A device of the character described comprising a casing member and an illuminating member located within said casing member, a window for permitting light from saidilluminating member to pass out of said casing member, a translucent member carried by said casing member and so disposed as to permit light from said illuminating member to pass out of said translucent member, an end cap carried by said casing mem- -ber and partially bounding said translucent member, said end cap being provided with an opening to permit light to pass out of said illuminating member, and a blinder lid mounted upon said end cap and movable relatively to said opening for the purpose of closing said openin Signed at l\ew ork city, in the county of New York and State of New York, this 29th day of February, 1924.
